Prior to the break up of the Soviet Union, Armenian clubs were part of Soviet competition.
Ararat Yerevan was one of just two non-Russian clubs to win the Soviet double, in 1973, with Nikita Simonyan at the helm. They also won the post-independence Armenian Double in 1993.

1Benfica also Doubled F.C. Porto in 1981 and 1983, and could have made it Treble, since the Supercup was already existent (since 1979): Porto not only saved a triple horror by winning the 1981 and 1983 Supercups, but filling the slot for European Cup Winners' Cup 1983–84 as 1983 Portuguese Cup runners-up, they even managed to reach the final, failing their first Quadruple in 1984 by a close margin.

2In 1974, Sporting was the first team to win the Double over the same team, making Benfica running up in both Liga and Cup. Almost winning a European Treble, Sporting saw 1. FC Magdeburg win 1974 Cup Winners' Cup after being eliminated by them in the semi-finals by one goal and after a series of misfortunes (two injuries, an own-goal at home, a missed penalty and a shot on the post). That year, Hector Yazalde established a record of goals scored in one Portuguese football season which still lasts to this day.

Six teams achieved the Double of the Soviet Top Liga and the USSR Cup in the former in the Soviet Union. The final Soviet championship was contested in 1991 and, following the breakup of the USSR, newly independent states organised their own national competitions, with UEFA holding the Russian Premier Liga as successor to the old Soviet Liga.

Currently in the United States, the Double may mean either the MLS Double, which is achieved by winning both the MLS Supporters Shield and the MLS Cup,[2] or a Liga/cup Double of either the MLS Cup or Supporters Shield, in addition to the U.S. Open Cup or Canadian Championship for United States and Canadian clubs, respectively. The Double may also be a combination of any of the domestic cups mentioned above and the CONCACAF Champions Liga.

A rarer, and less coveted, domestic double is that of winning the Liga championship and the Liga Cup. In many Ligas this can not be done as there is no second domestic cup competition (as in Italia and the Netherlands) or it has been disbanded (such as in Spain and Denmark). The format of Liga cups and the number of participating teams can vary enormously from one Țara to another. In the case of Germany, it should be noted that the DFB-Ligapokal was played in the summer months prior to the Bundesliga and therefore was won in the preceding calendar year to the title win.

A very rare event. A Trans-State double occurs when a club wins a Liga and a cup which technically belong to two different countries and different associations. This happens as a result of a change in the political situation in the club’s home Țara. There are two useful examples:

In the same spirit as the European Treble, the European Double consists of winning the top tier European tournament (currently the UEFA Champions Liga) and domestic Liga title in a single season or calendar year. This has been achieved on 23 occasions by 15 clubs from 56 European competitions. FC Barcelona has achieved this on the most number of occasions (4). Ajax Amsterdam and Real Madrid are the only teams that have successfully defended a European Double. Jose Mourinho has the unique distinction of being the only manager to achieve this double with two different clubs, having done so with F.C. Porto (2004) and Internazionale (2010).

The UEFA Europa Liga (formerly the UEFA Cup), with a domestic Liga title win, offers the chance for a club to win a lesser European double; but arguably a more prestigious achievement than a domestic double. This has been completed on fourteen occasions.

Simlarly, there were six occasions of clubs winning their Liga and the now defunct UEFA Cup Winners' Cup (CWC). No club ever won the CWC as part of a recognised treble. In the case of FC Mageburg and Dynamo Kiev, it is also worth noting that the domestic Championships they won are also now disbanded, due to German reunification and the disintegration of the Soviet Union respectively.

A Domestic Cup Double consists of winning both domestic cup competitions in a single season or calendar year (for Sezoane when this double was won in conjunction with the Liga title see Domestic Treble). Examples include:

There have been several occasions when a club has won its Association's cup or Liga Cup and a UEFA trophy but not its Liga title. For European cup doubles won in conjunction with the Liga title, see The Treble.

A national team cannot usually win a FIFA World Cup and their continental championship in the same year because they are usually not held in the same year (except for the Africa Cup of Nations), but one which wins both titles consecutively could be said to have "done the double".

Sven-Göran Eriksson is the only manager to win a domestic double in three different countries, having done so in Sweden, Portugal and Italia with Göteborg (1981–82), Benfica (1982–83) and Lazio (1999–00) respectively. Note that this included back-to-back double wins in separate countries.
